DUAL FLUID SPRAY GUNS
OPERATING INSTRUCTIONS AND REPLACEMENT PARTS
INTRODUCTION:
These Manual Spray Guns require clean dry air pressure
regulated to provide from 6 to 8 C.F.M. at 40 to 60 lbs. air
pressure depending on size and number of atomizing
heads to be used. Paasche Regulator & Condenser
Units are recommended for attaching to air supply line to
remove water, oil, rust or scale and help insure quality
finish of coating. They have no parts that require
replacement and clean themselves each time the drain
valve is opened to remove accumulation of filtered
contaminates.
AIR AND FLUID CONNECTIONS:
1. Air Connection: To remove any accumulated
foreign matter blow out all hoses before using.
a. Air supply to Spray Gun must be turned off
before attaching fittings to the Air Inlet.
b. Attach HT-1/4 Air Hose to the Air Outlet on the
Air Regulator and Air Inlet on the bottom of
the handle on the Spray Gun.
2. Fluid Hose Connection: HPT-1/4 PVC Fluid Hose
with HPTSC-Stainless Steel Couplings should be
long enough to form a loop below the Spray Gun at
all times when using fluid hose to feed material to
the Spray Gun (two required).
a. Attach HPTSC-1/4 St. St. Couplings to the
fluid inlets of the two Fluid Bodies.
b. Attach opposite ends, HPTSC-1/4-3/8 St. St.
Couplings, to containers of respective
materials being sprayed.
3. Fluid Container Connection: When using USP-QT
(QT./.946 l) Plastic Bottle Assemblies, make sure
Screw Covers are tightened securely so fluid will
not leak at Bottle connections.
4. Tighten all Air and Fluid connections securely.
OPERATION:
1. After hose connections have been made, regulate
the air pressure to about 40 lbs. atomizing pressure
and then pull trigger back slowly.
a. The first 1/4" of trigger stroke opens the Air
Valve which operates the cylinder action of
the right side atomizing components.
b. Continued pull on the trigger opens both of
the atomizing Spray Heads for spraying.
2. The U-1460 Adjusting Nut (part 39) can be used to
regulate desired amount of fluid to the automatic
Spray Head and the 200-17 Fluid Knob (part 27)
can be used to adjust fluid to the manual side of the
two headed spray gun.
3. Dual Fluid Spray Guns are designed to atomize and
mix fluid materials outside the atomizing aircaps.
This prevents materials from hardening inside the
spray gun.
4. The U-28-12 Packing Washers (part 6) should be
replaced periodically.
a. Fill packing cavity with 3 new U-28-12
Packing Washers and replace U-29 Packing
Gland (part 7), DU-30 Spring (part 8) and U-
31 Spring Seat (part 9) in position.
b. A few drops of oil should occasionally be
applied to the U-2506 Piston Leather (part Z)
to keep it pliable.
